“…For the extraction of carotenoids, a protocol similar to that described earlier was followed [14]. Compounds were separated with an ACQUITY UPLC BEH RP C18 column (1.7 µm, 2.1 mm × 100 mm, Waters Corp., Milford, MA, USA) at 32 °C.…”

Triterpenoids, carotenoids, chlorophylls, and antioxidant capacity of individual parts of wild garlic at different times of harvesting were studied. Leaves, flowers, bulbs, and stems of Allium ursinum were used in this study. The contents of triterpenoids, carotenoids, and chlorophylls were determined by UPLC-PDA-Q/TOF-MS, and the antioxidant capacity was determined by ABTS and FRAP assay. A total of 21 compounds including 3 triterpenoids, 11 carotenoids, and 7 chlorophylls were identified in anatomical parts of A. ursinum in March and June 2016. These compounds present in individual anatomical parts of wild garlic were determination in this study for the first time ever. The average content of total triterpenoids ranged from 750.7 to 4159.5 mg/kg dry matter (dm) and that of carotenoids and chlorophylls ranged from 14.4 to 14,424.5 mg/kg dm for bulbs and leaves. The average level of the antioxidant capacity ranged from 37.1 to 91.7 µmol Trolox/g dm in bulbs and leaves, respectively. The leaves, flowers, and stems of wild garlic are a good source of health-promoting compounds. They can be used as functional food ingredients, dietary supplements, and additives.

“…Commonly used solvents for lycopene extraction are ethanol, hexane, acetone, ethyl acetate, chloroform dichloromethane, isopropanol, and petroleum ether [157][158][159]. As lycopene is insoluble in methanol (a solvent widely used for carotenoid analysis), it requires several extraction steps, which involves higher volumes and a more complex treatment of the extracts.…”

“…Diethyl ether (Et 2 O) must be freshly prepared (peroxidefree) before use [52]. Magnesium carbonate [159,166] or calcium carbonate [168] is often added during the extraction process to neutralize organic acids that might be present in the sample [175,179,180].…”

“…In general, HPLC can be used to analyze almost all the compounds in the herbal medicines. Thus, over the past decades, HPLC has received the most extensive application in the analysis of herbal medicines [63][64][65][66][67][68][69][70][71][72][73][74][75][76]. Reversed-phase (RP) columns may be the most popular columns used in the analytical separation of herbal medicines.…”

Different chromatographic and electrophoretic techniques commonly used in the instrumental inspection of herbal medicines (HM) are first comprehensively reviewed. Chemical fingerprints obtained by chromatographic and electrophoretic techniques, especially by hyphenated chromatographies, are strongly recommended for the purpose of quality control of herbal medicines, since they might represent appropriately the "chemical integrities" of the herbal medicines and therefore be used for authentication and identification of the herbal products. Based on the conception of phytoequivalence, the chromatographic fingerprints of herbal medicines could be utilized for addressing the problem of quality control of herbal medicines. Several novel chemometric methods for evaluating the fingerprints of herbal products, such as the method based on information theory, similarity estimation, chemical pattern recognition, spectral correlative chromatogram (SCC), multivariate resolution, etc. are discussed in detail with examples, which showed that the combination of chromatographic fingerprints of herbal medicines and the chemometric evaluation might be a powerful tool for quality control of herbal products.
